Move additional cache values out of UI module and into base. [#3292076]

Problem/Motivation

If you disable the Purge UI module, but have set the value of you caching to a higher value from the UI module, you will see the page report "no caching". It's pretty typical for production environments to disable UI-based modules so this should probably be moved into the base module.

Steps to reproduce

- Install purge UI
- Set the cache to any value provided by the UI module (i.e. 1 month)
- Uninstall purge UI
- Navigate to cache settings page (/admin/config/development/performance)
